Importance:
Some populations of this species in the Barberton region of South Africa have evolved the ability to hyperaccumulate nickel, making this species ideal for a comparative genomics approach to understand the evolution of this extreme phenotype.

Importance:
The Red List of Southern African Plants notes that the species is range-restricted species (EOO 260 km²) and 'declining due to ongoing habitat loss and degradation'. A recent publication by Milton et al. (2024) studied eight populations and concluded that grazing and climate change appear to be contributing to declines in this endemic habitat specific dwarf succulent, already threatened by land transformation and poaching in the Succulent Karoo hotspot of South Africa.
